' Application filed ma '11,

This invention relates to t'ool locking de-. vices, and the saidinventionis-partieu'larly' adapted for use in locking what are knownasdrills, especially those designated as jack hammer drills. Drills ofthis character are usually of a size or length which precludes theirbeing stored in the usual tool boxes provided for containing equipmentof rail road repairmen or gangs, as they are commonly referred to. s

It is an ob 'ect of this invention to provide novel means whereby aremovable anchorage may be supplied for securing a tool holder to thebase of a rail or part of a railway track, and to associate therewith atool retaining clamp which may be secured by a lock against theft of thetools held thereby.

It is a further object of this inventlon to produce an anchor and lockclamp which can be expeditiously manipulated for securing or releasingthe tool held by the clamp or holder; and furthermore, to provide novelmeans whereby the anchor may be expedr. tiously applied to or removedfrom the rail or element to which it is secured. By reason of theprovisions just stated, the tool securing device may be applied to atrack at any location and this may result in preventing the necessityfor transporting the tools to and from fixed locations.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail,reference will be had to theaccompanying drawings forming part of this application, wherein likecharacters denote corresponding parts in the several views, and. in

which- I Figure 1 illustrates a view in perspective of a tool holdingandsecuring device embodying the invention;

Figure 2 illustrates a detail view of the clamp; and

Figure 3 illustrates a top plan view thereof.

In these drawings, 5 denotes a bar of metal and 6 a coacting bar,preferably connected together at one end by a pivot 7 by which the twobars may be swung to permit the insertion between them of a tool 8 suchas a drill. The facing edges of the bars are provided with coincidingrecesses suchas 9 which produce clearances and seats in which 1am,-Serial mt 190570;-

the tool or a portion thereof may be inserted andfretained-Preferablyione of the bars is provided with a slot or opening 10 nearone of its ends, andashere shown, the bar 6 has this characteristic. Thecoacting bar 5, in the present embodiment, carries a hasp or loop llwhich projects through the opening 10 to a degree that it will receive alocking device of appropriate type, by which the two bars may beretained in their operative positions. 7

In the present embodiment of the invention, a lock 12 is associated witha chain '13 and the chain 13 in turn is secured to an anchor through theemployment of another lock 1 1, by which an anchor of the tool holder isreinovably secured to the rail of a track. In the present embodiment, ofthe invention, the anchor just mentioned comprises a plate 15v which maybe inserted under the base 16 of a rail, and the said plate as the haspof a lock such as 14. This plate 7 with the parts just describedconstitutes one element of the anchor, and the other element, in thepresent embodiment of the invention, consists of an angle iron, oneflange 18 of which is provided with an aperture 19 to receiveor fit onthe end of the plate 15, whereas the other angle or flange 20 of theelement extends across and is intended to engage the base flange of therail opposite that engaged by the hook 17 of theplate 15. The provisionof the lock for holding the parts of the anchoring element assembled orin operative position permits the use of the anchor and the tool holderat different locations, since the operator need only'secure the anchorto a rail and the tool holder to a connection between the anchor and thetool holder when the tool holder is to be stored, and thereafter, thetool holder may be removed from the connection without disturbing theanchor, or the anchor can be removed when it is desired to change thelocation for storing the tool.

I claim: 7

1. In a tool locking device, elongated elementspivotally connectedtogether near one end, the said elements having coinciding recesses intheir opposed faces, means for securing the ends of the members oppositethe pivots, means for anchoring the aforesaid structure, said meanscomprising a plate having a flange, the said plate being adapted to beinserted under the base of a rail With the flange of the plate embracingthe base flange of the rail, a coacting clamping 'ele' ment having anaperture to receive the first mentioned plate and provided with a flangeoverlying the other base flange of the rail, means for securing thecoacting anchoring elements together, and a connection between theanchor and the said tool holder.

2. In a tool locking device, elongated elements pivotally connected.together near one end, the said elements having coinciding recesses intheir opposed faces, means for securing the ends of the members oppositethe pivots, means for anchoring the aforesaid structure, said meanscomprising a clamp adapted to be removably secured to a rail, means forlocking the clamp against removal, a connection between the elements,and means for locking the said connection to the said elements. 7 JOHNBRANICK
